FRANK lVI. SAYFORD, OF BROOKLYN, NEW YGRK.

COOLNGr DEVICE.

Application led November 30, 1921.

To all lwhom it may concern.'

Be it known that I, FRANK M. SAYFORD, a citizen of the United States, residing in Brooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Cooling Devices, of which the following is a specification.

My present invention relates to cooling devices, and `particularly to a cooling device for butter-chips, and one object is to provide a device of this character for use in connection with restaurants and dining rooms.

Another Objectis to provide a cooling device comprising acooling portion and a container portion, the container portion being comprised of a plurality of container parts or members and being separable as a whole from the cooling portion for distribution of the material cooled therein, or the parts or members comprising the container portion being separable from each other for convenient distribution of the material appurtenant to such container part or member which has been cooled in the container portion.

Another object is to provide a cooling device comprising a cooling portion and a container portion, the container portion being comprised of a plurality of container parts or members and being capable of enlargen ment by the addition of similar container parts or members.

In the accompanying drawings which show one of the possible embodiments of my invention and which form part of this specification, Figure 1, is a sectional yview showing the cooling portion and the container portion overlying the cooling portion and comprised of a plurality of container members or trays.

Figure 2 is sectional view on the line 2-2 of Fig. 1.

Figure 3, is a perspective view of one of the container members or trays.

Figure 4, is a detail sectional view on an enlarged scale of one of the material holders or butter-chip holders used in association. with the container members or trays.

Figure 5, is a fragmentary detail sectional view, on an enlarged scale, of a side and a portion of the bottom or floor ofr a container member or tray, with a corresponding portion, in outline, of a container member or tray in fitting or conforming engagement with the first container member or tray and in overlying relation thereto.

Serial No. 513,919.

Similar reference characters are used to denote similar parts throughout the several views.

My invention comprises the cooling portion generally denoted by A, vthe container portion generally denoted by B, the container members or trays generally denoted by C, and the material holders, or butterchip holders, generally denoted by l).

The cooling portion A preferably is of box form, open at the top, and preferably is made of sheets of meta-l soldered or otherwise secured together to provide space be tween the exterior and interior sheets for receiving suitable heatinsulating filler, such as charcoal or saw-dust. The container portion A for convenience is not shown in Figs. 1 and 2 of this construction, but preferably is substantially similar in construction to the construction of the trays shown in Fig. 5, and will be readily understood by reference to this figure. The portion A has at the upper edge of its side and end walls an interior rabbet providing the ledge 10 and the upward extension 11.

The cooling portion A is divided into the ice chamber 12 and the fan chamber 13, the fan chamber being open at its top and formed by a rectangular sheet of metal 14 flanged or otherwise suitably secured to an interior wall of the cooling portion A and extending from the bottom to within a short distance of the top thereof. The fan chamber 13 has an aperture 15 therein about midway of the height thereof, the purpose of which is later mentioned. The motor driven fan F, the motorv of which preferably is electric, is secured in the chamber 13, the fan being above the upper line of the aperture 15. The ice chamber 12 has at one side at the bottom an aperture 16 communicating with the atmosphere, or communicating with means, not shown, for providing pre-cooled air. The coil of piping 17 is arranged in the ice chamber 12, one end of the piping communicating with the aperture 16 and the other end being flanged to the wall 14 and communicating with the aperture 15 before mentioned.

Each of the trays C has side andend walls preferably formed of two sheets of metal soldered or otherwisesecured together to provide space therebetween for receiving hea-t insulating filler, Fig. u5, the side and end walls having at the upper interior edge a` rabbet providing a ledge 18 and anfupn portion A by engagement of the downward lia l shown in Fig. 5, and may be oit paper, wood extension 21 with the ledge 10 and engage` ment oi the bottom-tace 20 with the upward extension 11 ot the cooling portion A, and conformably engage or fit, a similar overlying tray C by engagement oi the downward extension 21 and bottom-face 2O of the overlying tray with the ledge 18 and upward extension 19 ot' the underlying tray, the overlying and underlying trays when so engaged forming a hoxlile container portion. l

Each tray C has a floor or bottom 22, preferably formed ot a metal sheet iianged or otherwise secured to the interior side ot' the extension 21 thereof. Each bottom 22 has openings therethrough such as the alined and spaced slits 23 for passage ot air, and has apertures therethrough, such as the alined and spaced apertures 2st, 'for receiving the material holders or butterfchip holders D therein. But instead of apertures such as 24 the bottom or floor may be provided with indents, not shown, or other suitable means for retaining the holders D in the trays.

The cover 25 is provided for the container portion, this cover preferably having interior space, not shown, tor insulating filler, and having through it apertures such as 2G for passage of air from the container portion. The cover 25 has in its under edge an all around rabbet providing a shoulder 27 and a bottom-face 28, the shoulder 27 being engageable with the ledge 18 and the bottonrface 28 being engageable with the upward extension 19 of a tray t) when the cover 25 is in covering position.

The material holders or butter-chip holders D preferably are of the saucer-like form 7 metal or any suitable material.

In assembling and operation: The cooling portion A being constructed and arranged as described, ice is placed in the chamber 12 over and around the coil oit piping 17. A trayC having thereon material to be cooled, preferably in holders such as D, is arranged in overlying fitting or conforming engagement with the cooling portion A. A second tray C having thereon material to be cooled is arranged in similar overlying engagementwith the first tray,and so continued until the desired size, of container portion is formed. The cover 25 is arranged in overlying engagement with the uppermost tray, the fan F is started and air admitted to the coil of piping 17 and cooled by the ice in the chamber 12, is forced as a cooling current through the container portion B and over and around the material on the trays C.

Laien?? For distribution of the cooled material one or more of the trays (l may be littcd from engagement with its associated trays and carried to any convenient position; or the whole container portion A with the cooled contents may be moved bodily to a desired position b v lifting the lowormost tray, and its associated trays 'torming the container portion B, from engagement: with the cooling portion A.

It will be noted trom the 'foregoing de scription that the container portion is cxtensible or capable of enlargement by the addition ot trays C, such extension or eulargement being only limited by the ability of the cooling portion A to cool the contents of the enlarged container portion.

For draining the ice-chamber 12 suitable drainage means, such as the outlet may be arranged in the ice-chamber below the coil of piping 17.

And it' desirable a door or doors. not shown, may be provided in the wall ol the cooling portion A ttor access to the icechamber 12 and the vtan chamber 13.

I thus provide a cooling` device which is simple in construction, and convenient; in use, and which, due to the scparability otl its parts, the easy access to its interior and to its being preferably otI metal, is easily cleaned and sanitary.
